WALL-PAPER TRHVHVIING AND PASTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 708,419, dated September 2, 1902.

Application filed April 18, 1902.

To ctZZ whom, it may concern:-

Be it known that I, JACOB P. SPROOT, a citizen of the United States, residing in the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Wall-Paper Trimming and Pasting Machines, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawings, forming part of this specification. I

My invention relates to a machine for use in applying paste to wall-paper and trimming the edges of the paper.

The invention also relates to means for slitting the paper into narrow widths and tomeans for rewindingthe paper where the roll is wound in a direction to that utilizable in a machine of the class to which myinvention pertains.

My invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

FigureIis a top or plan view of my machine. Fig. II is an end elevation of the machine. Fig. III is a vertical cross-section taken on line III III, Fig. I. Fig. IV is a vertical longitudinal section taken on line IV IV, Fig. I. Fig. V is a vertical cross-section taken on line V V, Fig. I. Fig. VI is a top View showing in detail one of the adjustment-rods by which the slitting-cutters are heldto the roller at which they operate. Fig. VII is an enlarged vertical section taken on line VII VII, Fig. I; Fig. VIII is a View in elevation of the main driving-gear wheel andratchet, the view being'partly'iin section, taken on line VIII VIII, Fig.,IX. .Fig. .IX is an enlarged section taken on line IX IX, Fig. II.

1 designates the end walls of the frame of the machine, that are joined by cross-pieces 2 and 3. (See Figs. I and III.)

4 represents bracket-arms forming extensions carried by side plates 5, that are attached to the frain'eend walls, as seen in Figs. I and II.

6 designates a longitudinally-movable rod loosely mounted in the bracket-arms 4, the said rod being provided at one end with a non-circular portion 7, that fits in a correspondingly-shaped aperture in the bracket- Serial No. 103,575. (No model.)

arm in which it is mounted and being provided at its opposite end with a screw-thread 8. The threaded end of the rod 6 receives an adjustment hand nut 9, that is rotatably seated in and held by an embracing-collar 10, fixed to the bracket-arm 4, occupied by the threaded end of the rod 6, as seen in Fig. IV. By turning the hand-nut 9 the rod 6 may be moved longitudinally within the bracket arms 4.

11 and 12 are uprights provided, respectively, with slots 13 and 14, in which a rod 15, that receives the delivery-roll of paper A, (see Figs. I and III,) may be seated. The upright 11 is provided with a collar 16, that is fitted to the rod 6 and held by a set-screw 17. The upright 12 is carried by a sleeve 18, that is loosely mounted on the rod 6 and is provided with a longitudinal slot 19, that receives a guide-pin 20, which passes therethrough and is seated in the rod 6. The sleeve 18 of the upright 12 is connected to the upright 11 by a retractile spring 21, the tendency of which is to draw the loosely-mounted sleeve 18 and the upright12 toward the upright 11 to hold the roll of paper firmly between said uprights to provide for an even delivery of the paper from said roll.

22 designates a housing supported by the frame end walls 1. (See Figs. III and IX.)

'23 is a shaft that is loosely mounted in one of the frame end walls and passes through the other end wall and is supported bya setscrew 24, that is seated in a housing 25, attached to the last-named end wall.

26 is a coil-spring held at one end by attachment to the frame of the machine within the housing 22 and having its opposite end 27 attached to the shaft 23. (See Fig. IX.)

28 is a gear-wheel loosely mounted on the shaft 23, between the frameof the machine and the housing 25, the said gear-wheel being backed by a collar 29, that is held to said shaft.

30 is a drum fixed to the shaft 23 beside the gear-wheel 28, and 31 is a tape attached to said drum and adapted to be wound thereon. The tape 31 is provided at its outer end with a loop 32, that serves as a handheld to be engaged for the purpose of drawing upon the tape, and thereby causing the rotation ofv the drum 30 to impart like movement to the shaft 23.

33 is a pawlpivoted to the drum 30 and backed by a spring 34. (See Figs. VIII and IX.) The pawl 33 is adapted to engage the teeth of a ratchet 28, carried by the gear wheel 28.

From the foregoing it will be seen that upon pulling the tape 31 outwardly rotation is imparted to the drum 30 and shaft 23, that serves to put the spring 26, attached to said shaft, under tension and at the same time to operate the pawl 33in engagement with the ratchet 28 to rotate the driving gear-wheel 28. Upon the release of the tape 31 the spring 26 unwinds and rotates the shaft 23 and drum 30 reversely, so that the tape is again wound onto the drum, while the pawl 33 slips over the teeth of the ratchet 28 to again engage them ready for action on the next operating pull exerted upon the tape 31.

35 designates a slotted boxing attached to the machine-frame above the gear-wheel 28, and mounted in said boxing is a pair of boxes 36 37, adjustable in the slot of said boxing and containing, respectively, bearing-screws 38 and 39. (See Figs. II and VII.)

40 is a shaft rotatably upheld by the bearing-screw 38 and having fixed thereto a pinion 41, that meshes with the driving gearwheel 28 to impart rotation to the shaft 40.

The pinion 41 in turn meshes with a pinion 42, fixed to a shaft 43, that is rotatably supported by the bearing-screw 39. The shaft 43 bears a roller 44, (see Figs. I and III,) located intermediate of the ends of said shaft. The opposite ends of the shafts 40 and 43 are supported by bearing-screws 45, (see Fig. 1,) mounted in a boxing 46, similar to that described, at the opposite end of the machine.

47 represents cutters adjustably fitted to the shaft 43, to which they are held by setscrews 48.

49 designates trimming cutters loosely mounted on the shaft 40 and adapted to bear against the faces of the cutters 47, to which they are held for cutting action by pressuresprings 50, that bear against the collars of said cutters 49, the said springs being held by set-collars 51, adjustably applied to the shaft 40.

On the shaft 43, within the boxing 46, is a gear-wheel 52, that meshes with a gear-wheel 53 on a shaft that bears a feed-roller 54, (see Fig. III,) by which the paper is fed through the machine. On the roller 54 is a covering 55, preferably of cloth.

' 56 is a pressure-roller positioned above the feed-roller 54, so as to rest upon the paper that is passed'over said roller. The pressureroller 56 is journaled in pivoted bearing-bars 57, that are loosely connected at 58 (see Fig. III) to the uprights 5 of the side plates 5.

59 is a pasting-roller journaled in the franie end walls 1 and provided with a covering 60, preferably of cloth, and 61 is a guide-roller also journaled in the frame end Walls and'beneath which the paper travels in its course to the pasting-roller, as indicated by dotted lines, Fig. III.

62 designates a paste-pan located beneath the pasting-roller 59, so that said roller may turn therein. The inner end of said pastepan is mounted upon a rest 63, and the outer end is supported by a catch 64, that engages beneath the rim of the pan and is held thereto by a spring 65, so that upon the release of the catch the pan may be readily removed from its supports. The pasting-roller 59 is driven by a pinion 66, that meshes with the driving gear-wheel 28 and in turn communicates power to a gear-wheel 67, fixed to the shaft of said pasting-roller within the housing 68.

62 is a sloping drip-plate situated beneath the feed-roller 54 and adapted to receive the paste that falls from said roller and return it to the paste-pan 62.

69 designates a shaft journaled in swingbars 70, that are pivoted to the frame end walls 1 at 71. (See Figs. III and V.) The shaft 69 is preferably scaled, and adjustably mounted on the shaft are slitting-cutters 72, adapted to be held to the shaft by set-screws 73. The slitting-cutters 72 are adapted to be moved to the roller 44, that occupies a central position of the shaft 43, and when in such position serve to slit the paper into narrow widths as it traverses said roller and is drawn between the roller and the slitting-cutters. The bearing-bars 70, that carry the shaft of the slitting-cutters, are yieldingly held toward the roller 44 to maintain the slittingcutters in proximity to said roller, the means for so holding the bars comprising springs 74, the forward ends of which are connected to the bars and at their rear ends are attached to adjustment-screws 75, that pass loosely through lugs of supporting-brackets 76, attached to the insides of the frame end walls 1. (See Fig. V.) In the rear of the lugs of the brackets 76 are adjustment-nuts 77, that are applied to the screw and bear against the bracket-lugs for the purpose of accomplishing the adjustment of said screws to a degree that will cause the springs 74 to exercise a desirable pull upon the bearingbars 70 to hold the slitting cutter in the proper relation to the roller 44.

78 represents keepers that inclose the bearing-bars 70, and seated in said keepers are stop-screws 79, against which the rear edges of the bearing-bars are adapted to rest to limit their rearward movement, so that the slitting-cutters on the shaft mounted in said bearing-bars will not be drawn directly into' contact with the rollers 44 and their edges be thereby dulled.

For the purpose of rewinding rolls of paper that are originally factory-wound with the face of the paper outermost on the roll I employ mechanism that I will now describe.

The upper ends of the uprights 5 of the side plates 5 are provided with slots 5". (See Figs. I and III.) In the bearing provided by these slots I introduce a spool consisting of a rod 80, having a V-shaped strip 81 applied thereto to render the spool non-circular in cross -section and which is adapted to receive the end of the paper applied thereto to be wound around a spool. By reason of the shape of the spool the paper is prevented from slipping in winding it thereon. The rod 80 is held in the slotted uprights by piv oted catches 82, held by springs 83. III.) In operating the spool to Wind the paper thereonto power is communicated from the pasting-roller gear-wheel 67 through a gear-wheel 84, that in turn meshes with the pinion 85, that is fixed to the spool-rod 80.

In the practical use of this machine in applying paste to wall-paper and trimming the edges of the paper the roll of paper to be used is mounted on the rod 15, set into the uprights 11 and 12, carried by the longitudinally-movable rod 6, and held therein in the manner hereinbefore stated. The end of the paper is then passed beneath the guide-roller 61 and over the pasting-roller 59, from which it is passed to the feed-roller 54 and between said last-named roller and the pressure-roller 56. The course of the paper is then continued between the trimming-cutters 47 and 49, by which it is trimmed and delivered from the machine in a condition ready for application to the wall that is to receive it. Where the paper is to be slit into narrow widths, it is passed upwardly between the roller ME and the slitting-cutters 72, instead of moving directly away from the machine as it leaves the trimming-cutters.

The operation of the various driving parts of the machine have been heretofore fully stated, and it is considered unnecessary to refer to them further regarding their operation to obtain the uniform working of all of the parts of the machine.
